When your friend’s Rooms are active, you’ll see the video camera icon pulsing!
Open the Rooms icon. Active Rooms will appear at the top. You can also use the Room Search to find the exact Room you’re looking for.
The Room will also appear as live on your desktop with a green outline if the Room has been added to your desktop:
Note: If your friend hasn’t called you to the Room or sent you the Room link (if you’ve never been in the Room before) then it won’t appear in your Rooms list as active.
